IMPROVED FOLDING CHAIR.

Specification forming part of Letters Patent No. 37,864, dated March 10,1863.

To au whom, it may concern:

Be it known that we, HENRY SMITH Go- LIGHTLY and CHARLES S. TWITCHELL,both of the city and county of New Haven, in the State of Connecticut,have invented certain new and useful Improvements in Folding Chairs 5and We'do hereby declare the following to be a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, making part of this speciiication, in which- Figure l is aperspective view of a chair set up or open for use. Fig. 2 is a sideView of the same unlocked preparatory to folding. Fig. 3 is a side viewof a chair folded. Figs. 4 and 5 illustrate the manner of locking thechair when set up.

Same letters refer to like parts.

Our invention consists in a constructive mechanism, whereby we areenabled to produce a folding chair, compact when folded, and when set upso firmly locked as to be movable without of itself unfolding-a greatdifficulty common in all folding chairs,1 and to overcome which is theobject of our invention.

To enable others skilled in the art to make and use our invention, wewill proceed to describe its construction and operation.

We construct the curved parts of our chair from wood bent to therequired curve, but it may be cut or other material used. Bending,however, is the strongest and wood the best.

A A are the two front legs, curved so as to form a part of and jointedto the arms B B by hinges c, as shown in Figs. l and 2, and lockedtogether by the catch e, (see Fig. 4,) or may be by a latch. C C are theback legs, pivoted to the arms B at c. i is a rundle to sustain the legsC C in their proper position. D is the seat, pivoted by each side S tothe legs C C at d, and by a notch, o, on each side, or its equivalent,lock onto a rundle, E. (See Fig. 5.) The rundle E, with a second rundle,F, holds the front legs, A A, in their proper position relatively toeach other. H H are slats connecting the two arms B B, and form the backof the chair.

To fold the chair, turn the catches e, (see Fig. 4,) which lock thefront legs to the arms from the locked position shown in black, Fig. 4,to as shown in red, same figure. This unlocks the joint ofthe arms andlegs. Then raise the seat, as see Fig. 2, so as to relieve the rundle Efrom the notches o on the sides of the seat, which operation willrelease the several parts, when they may be folded, as shown in Fig. 3.

To set up the chair, reverse the several operations and lock, as beforedescribed.

We claim- The combination and arrangement described of the legs A A,back or arms B B, legs C C, and seat-bars S, when the same operate tofold and lock in the manner substantially as herein specified.
